STOP-MOTION FOR PREPARING. SPINNING, AND DOUBLING MACHINES.

SPECIFICATION forming part of Letters Patent No. '7' 19,668, dated February 3, 1903.

Application filed May 6, 1901.

T0 at whom it may concern:

Be it known that 1, WILLIAM HILTON, engineer and machinist, a subject of the King of the United Kingdom of Great Britain and Ireland, and a resident of 97 Windsor road, Oldham,in the countyofLancaster,England,have invented a new and useful Improvement in Automatic Stop-Motions for Preparing, Spinning,and Doubling Machines,of which the following is a specification.

This invention consists of an improvement in automatic stop-motions for preparing, spinning, and doubling machines, and is especially applicable to stop-motions for stopping slubbing, intermediate, and roving frames when the bobbins have attained the desired size.

The object of this invention is to provide an automatic stop-motion which shall act with greater certainty, promptitude, and precision of action and be less liable' to Wear and derangement than the arrangements of mechanism hitherto employed and shall be capable of being arranged to stop the machine in which it is employed at any diameter of the bobbins or other bodies into which the slubbings, rovings, or yarns are wound, as may be desirable, and in any desirable position in the lift or movement of the bobbin-rails or other corresponding parts.

A stopmotion provided according to this invention may, as is illustrated in the form illustrated by way of example in the accompanying drawings as arranged for application to slubbing, intermediate, and roving frames, be arranged so that when the frame has been automatically stopped at the completion of a set of bobbins the stopmotion retains the strap or belt on the loose pulley and prevents the attendant putting the strap or belt on the fast pulley and starting the frame again until the cone-strap has been moved back into the position for commencing a fresh set of bobbins. r

In the accompanying drawings, Figure 1 is a transverse section of so much of the mechanism employed in a slubbing, intermediate, or roving frame with a stop-motion provided according to this invention applied to it as is requisite for the illustration of this invention. Fig. 2 is a side View, partlyin longitu dinal section, of the mechanism employed ac- Serial No. 58,974. (No model.)

cording to this invention and the parts of the slubbing, intermediate, or roving frame with which such mechanism is arranged to act and showing the parts in the positions which they occupy during the filling of the bobbins. Fig. 3 is a longitudinal section corresponding to part of Fig. 2, on a larger scale than Fig. 2, and showing more clearly the arrangement of the stop-rod and catch rod or lever and the means provided to lock the stop-rod in position to keep the belt or strap on the loose pulley when the frame has been automatically stopped on the completion of a set of bobbins. Fig. 4 is a transverse section taken substantially on the plane indicated by the line A A of Fig. 3 and showing the arrangement of the upper end of the catch rod or lever. Fig. 5 is a side view, partly in longitudinal section, showing substantially the same mechanism as is illustrated in Fig. 2 and showing the parts in the positions which they occupy when the frame has been automatically stopped on the completion of a set of bobbins.

In the drawings, a is the usual stop-rod,

- frame, or roving-frame for operating on the setting-on rod 1), which carries the strapfork used to move the driving-belt into and out of position to drive or stop the machine. As shown, the stop-rod ais arranged in brackets c d, fixed upon the roller-beam e of the slubbing, intermediate, or roving frame, and is provided with a collar f, adjustable and secured by a set-screw g to act against a forked arm h, secured to the setting-on rod 5. A spring 2' (shown onlyin part) is secured at one end to the stop-rod aand at the other end to the bracket 0. The spring 01 is provided to move the stop-rod ain the direction indicated by the arrow B when the frame is to be automatically stopped. The setting-on rod 1) and the means by which it controls the belt employed being of the ordinary wellknown arrangement, a portion only of the setting-on rod 1) is indicated in the drawings.

. j is the usual longitudinally-movable rack employed to traverse the belt upon the cones usually employed in the machine, which being well known are omitted from thedrawings. During the working of the machine the rackj is gradually moved in the direction indicated by the arrow 0.

ICO

The rack j is made to receive motion in the usual way by means of the pinion 7c, shaft m, and bevel-wheels n 0 under the control of the usual mechanism used to regulate the winding, which being ordinary and well known is not indicated in the drawings.

19 is the usual anchor-bar bracket, carried by and moving with the lifting or bobbin rail qandservingin the ordinary way to gradually shorten the lift or up-and-down movement of the lifting-rail qby the usual means,which being well known are omitted from the drawings.

According to this invention a catch rod or lever r is suspended from the stop-rod a and is adapted to be engaged in any suitable way therewith, so as to retain it in position and prevent it from acting on the setting-on rod 1) until required to act automatically to stop the frame and prevent it frombeing restarted until the bobbins have been doffed and the cone-strap has been moved into the position proper for the commencement of a new set of bobbins. Preferably the catch rod or lever r is arranged so as to be incapable of becoming displaced from the stop-rod a. As shown, the catch rod or lever r is arranged to pass through a slot sin the stop-rod a and provided With a T-shaped head If, by which it is normally suspended from the stop-rod a. The said head 25 ot' the catch rod or lever r is arranged so as to be engaged during the working of the machine in a notch 11., formed in such stop-rod a. The catch rod or leverr may be guided in any suitable way. As shown, it is guided at the upper part by means of the slot 8 in the stop-rod a. The catch rod or lever r normally rests againsta stop '1) on a projecting bracket 10, formed on and extending downward from the box 01:, secured to the roller-beam e to carry and cover the locking-catch y, to be hereinafter mentioned, and aprojection .2, formed on the inside of the top of the box 00, serves as an abutment to prevent the catch rod or lever r from beingcarried along by the stop-rod a in its movement. The catch rod or lever r is arranged to be oscillated laterally by means of an adjustable stop bracket'or projection 2, mounted upon or arranged to be moved by means of the rack j. As shown, the adjustable stop bracket or projection 2 is secured by means of a bolt 3 to the movable rack j, which is formed with a slot 4 to permit the adjustment of the bracket 2. A spring 5, secured, for instance, by a set-screw to the bracket 2, serves to hold the catch rod or lever 1" in the position in which it is indicated in Fig. 2 against the stop Q) on the bracket to except at such times as it is moved from it by means of the adjustable stop bracket or projection 2. lever 1' carries a bracket 6, adjustable up or down thereon and secured in the desired position in any suitable way, as bya set-screw. The bracket 6 has a stud '7 secured in it, and upon this stud is pivoted a tumbler-catch 8 in the form of alever weighted at one end, so

The lower part of the catch rod or as to tend to turn on the stud in the direction indicated by the arrow D. The tumblercatch 8 is free to turn or yield in one direction; but it is prevented from being turned in the opposite direction by a stop 9, formed upon the bracket 6 in such a way that the arm 10 of such tumbler-catch can be turned downward but not upward about the stud 7. An adjustable knocking-0E bracket 11 is mounted on some part connected with the bobbin-rail q, so that it can at times while moving upward act upon the arm 10 of the tumbler-catch 8 and cause the catch-rod r to be moved upward, as will be further explained hereinafter. As shown, the adjustable knocking-otf bracket 11 is secured by means of a set-screw on the anchor-bar bracket 19, and a slot provided in the knock-' ing-off bracket 11 permits its adjustment upon the anchor-bar bracket 19. During the working of the machine the anchor-bar bracketp moving up and down carries the knockingoff bracket 11 past the arm 10 of the tumblerlever 8 without acting thereon until the catch rod or lever r is moved laterally by the adjustable stop bracket or projection 2.

The arm or locking-catch y is capable of being turned by the catch-rod 'r on the stud 12, secured on the box so, in the direction indicated by the arrow E in Figs. 2, 3, and 5 and is arranged in any suitable way-as, for instance, by being weighted, as shownso as to turn in the opposite direction when not being acted upon by the catch rod or lever r. The arm or locking-catch y is provided with an arm or hook 13 to pass behind the catch rod or lever r, so as to be acted upon thereby. When the frame is at work, the stop-rod a is held in position by the catch rod or lever 0", which is held against the projection 2. While the catch rod or lever r is in engagement with the stop-rod a the setting-on rod 1) may be moved by the attendant in the direction indicated by the arrow F in Figs. 2 and 5 to stop the machine without moving or disturbing the stop-rod a, the forked part of the arm it simply leaving the collar f and returning thereto when the machine is again started by the attendant. The adjustable bracket 2, having been set to the right position to act on the catch rod or lever T when the bobbins have attained the desired size, will in due time come into contact with and move the catch rod or lever r and, moving it away from the stop 0), will bring the tumbler-catch 8 into the path of the adjustable knocking oflf bracket 11 on the anchor-bar bracket 29. This bracket 11 will act upon the arm 10 of the tumbler-lever 8 and lift the catch rod or lever 1 out of the notch 10, formed in the stop-rod a, when the latter being liberated the spring 2' will cause the stop-rod a to be moved endwise in the direction indicated by the arrow B and with it the setting-on rod 1), which moves the strap or belt onto the loose pulley, when the frame will be stopped. The side movement of the catch-rod r, before referred to, also liberates the locking catch or arm y, so that when the stop-rod ct has been liberated and made its movement the locking-catch y will engage into a notch 14, provided for it in the stop-rod a, and thus lock it and prevent the frame from being restarted until the rack j, carryingthe cone strap-forks, has been wound back in the direction opposite to that indicated by the arrow 0 to the proper position for the commencement of a fresh set of bobbins. In the winding back of the rack j the adjustable bracket. 2 will be withdrawn from contact with the catch rod or lever 1', when the spring 5 will again move the catch rod or lever 7' against the stop i;-that is to say, approximately to the position in which it is indicated in Fig. 2-and the locking-catch y will be disengaged from the stop-rod ct and unlocked. The stop-rod ct being then free to be moved, the setting on rod 1) may be moved in the usual way to put the belt onto the fast pulley,

when the catch rod or lever 1' will engage with the notch u, formed in the stop-rod a, and hold it in position, so that the setting-on rod will be free to be used again to stop and start the frame whenever required until, the bobbins having attained the desired size, the automatic apparatus again comes into operation and the frame will be stopped, as hereinbefore described. When the stop-rod a is moved in the direction indicated by the arrow B, the incline 15, leading from the notch u to the upper surface of the stop-rod a, raises the catch rod or lever r so as to lift the tumbler lever 8 clear from the knocking off bracket 1]., so that as the rack j is wound hack into position for the commencement of a new set of bobbins the catch-rod r is free to swing back into its normal position and eventually disengage the locking-catch y from the stop-rod ct. By the bracket 2 being secured nearer to or farther from the catch rod or 1ever r at the starting of a set of bobbins the extent to which the bobbins are filled before the automatic apparatus acts to stop the machine may be decreased or increased, as may be requisite from time to time. The adjust ment of the knocking-off bracket 11 affords a further means of adjusting the time of the automatic stoppage of the machine. By the bracket or and tumbler-catch 8 being secured higher up or lower down on the catch rod or lever r the position in the lift of the bobbinrail g at which the automatic stoppage of the machine takes place may be regulated as may be desirable.

The locking lever or arm y can obviously be dispensed with in cases in which it is not necessary to lock the machine from being restarted.

The arrangements hereinbefore described are certain and prompt in action and not liable to wear and derangement.
